FANS think about football 80 times a day on average - and that's not including any dreams about the game, new research* from Virgin Money shows.

The average fan thinks about the game once every 12 minutes during the day, a poll of more than 2,000 fans shows. And the research shows that if their team is battling for honours or to avoid relegation the thinking time goes up.

Virgin Money, which measures the cost of going to games through its Football Fans' Inflation Index, commissioned the research to find out how much time fans put into the game. And while the average is 80 times a day around seven per cent of supporters admit to thinking about the game once a minute.

Fans were asked to estimate how much in an average day - assuming eight hours sleep - they thought about the game. And Sheffield United fans emerged as the biggest thinkers - they managed 110 times a day compared to 104 a day for Charlton supporters ahead of relegation on Monday. Chelsea came in third on 90 with Man Utd on 79. Everton supporters manage to limit themselves to 43 times a day.

Virgin Money spokesman John Franklin said: "The old advertising slogan was "Eat Football, Sleep Football, Drink Football. It should be "Think Football" as well.

"Partners of obsessive football fans will be well aware of the sometimes frightening level of interest in the game by hardcore supporters and they'll be used to the occasional glazed look on the face of their loved ones.

"We all know that football can be expensive financially but this shows it also requires a lot of thinking as well. Supporters show huge commitment to their teams - and 80 times a day is pretty impressive. They might though consider thinking about a few other things as well."

The Premiership of thinking fans shows Sheffield United edging out Charlton at the top of the table which possibly proves that relegation worries are worse than dreams about honours.

The index is aimed at helping supporters keep track of the rises and falls in the costs of supporting their team. The company identified the match-day essentials fans buy and keeps tabs on increases and decreases.

At the launch of the index last year the matchday basket of goods cost £77.95 and now it's £91.46 - a rise of £13.92 or 17.8 per cent. An increase in the cost of match tickets and replica shirts are the main reasons behind the increase.

Virgin Money's Football Fans' Prices Index runs every three months and looks at the cost of a typical basket of goods monitoring the ups and downs of prices.

The firm's research team examines the cost of items such as a gallon of petrol; match tickets; food; alcohol; train tickets and replica shirts.
